Chemotherapy may cause brain injury, small study finds

The areas of the brain responsible for attention, memory and planning were less active in breast cancer patients who had chemotherapy compared with other breast cancer patients and those without cancer, according to a study in the journal Archives of Neurology. After examining the functional MRI results of 25 breast cancer survivors who underwent surgery and chemotherapy, 19 survivors who did not undergo chemotherapy and 18 women without cancer, researchers said that chemotherapy may lead to "neurotoxic brain injury."
